DIVIS'IBLE UPRIGHT PIANO.

SPECIFICATION forming part of Letters Patent No. 410,223, dated September 3, 1889.

Application filed August 20, 1888. Serial No. 283,215. (No model.)

To all whom it may concern.-

Be it known that I, WILHELM UMLAND, of the city, county, and State of New York, have invented certain new and useful Improve ments in Upright Pianos, of which the following is a specification.

This invention relates to an upright piano that is so constructed that the front section can be detached with facility whenever it is required in moving the piano in or out of houses with narrow entrance and staircase. Said front section includes the key bottom, keys, action, legs or console, bottom board, and bottom rail. The rear section contains plate-rest or back, with string-plate, &c. The

. connection of the front to the rear section is accomplished by peculiar locking devices at the upper and lower parts of the sections, as will be fully described hereinafter.

This method of detaching and connecting will avoid every irregularity in action, keys, or any other part, and therefore the tone of the piano will not undergo the slightest change.

I11 the accompanying drawings, Figure 1 represents a perspective view of my improved piano-case. A is the rear part. Bis the front part of the same.

Fig. 2 represents a piece of timber sawed on a bevel through the line This bevel will be shaped as shown in Fig. 7, a and Fig. (5, a. As this bevel is cut through the entire length of the piece, the result will be two pieces, which are marked in the drawing of Fig. 2 as a and a Fig. 7 shows a horizontal cut of Fig. 2.

Fig. 3 represents the inside view of the right rear side of the piano. A shows the side; Z), the foot; a, the connecting beveled pieces of timber, which are glued to the side A and will rest with their lower edges on top of foot Z). Foot 6 is connected with side A, as shown in Figs. 3 and 8.

Fig. 8 represents a plan view of Fig. 3.

Fig. 4 represents the right front side. a shows the front connect ng plate or part; c, the arm; 6, the leg or console with foot marked f. These parts will complete one front side. The two front sides, in connection with key bottom 1, bottom f, or bottom rail f will complete the front part of the piano-case. A plan view of Fig. 4 is placed under the same as Fig. 9.

Fig. 5 represents the part shown in Fig. at having one -half of the beveled piece as joined to the part shown in Fig. 3, on which the second part of beveled piece is fastened. In this figure are shown four blocks g g, arranged so that the upper part of the block is supplied with a nut h, to receive the screw 71. of the lower part of block. \Vhen the screws are tightened, the parts will be firmly drawn together.

Fig. 6 represents a vertical section of Fig. 5, front view. g on Figs. 5 and 6 represents a plate for the purpose of covering the lines a Fig. 10 below Fig. 5 represents a plan view of Fig. 5.

Fig. 11 shows a modification of the line on beveied pieces of Fig. 2, and will leave one of those pieces wider on top to serve, if desired, the purpose of replacing the wooden lock or screw-blocks by two angle-irons or brackets with screws and nut-holes. The same will be placed and fastened to the extreme edge of the backward part of beveled pieces, as Fig. 11, a a? and g g, will GX- plain.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. An improved divisible upright piano case, the front section of which is shorter than the rear section, and which, when the sections are placed together, rests on the feet of the rear section.

2. An upright-piano case divisible into 1011- gitudinal sections and provided with beveled pieces, (having a series of inclined planes,) lock blocks or brackets with screws and nuts, as described, for the purpose specified.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two witnesses.

VILHELM UMLAND.
